end of which is stepped in a hearing as 16 fastened to the bolster 5. This shaft 15 may be rotated in any suitable way, for example, by means of a hand crank as 17 suitably fastened to the upper end thereoh The shaft 15 has keyed thereto a pinion as is represented as meshing with a gear as l!) feathered on the screw shaft, or, as I have hereinbefore termed it. screw 8. The gear and intermeshing pinion are covered by a cap or roxing as 20 fastened to the deck or platform 2. The gear 19 moves with the deck 2 and relatively to the screw 8 as the deck is brought into liolizonialism. in practice, the hand crank 17 will be within convenient.

. reach of an attendant standing on the deck or platform '2 and it follows that when the crank shaft 15 is turned the two screws 8 and 9 will, through the operative connections with said shaft. be simultaneously turned or so as to angularly adjust the bolster 5 with respect to the axle 3. The front-bolster is, of course, correspomlingly adjusted. I arrange between the deck 2 and the front axle 4 jacks which are shown in Figs. l and 3. and one of which will be now specifically described. Other means, however, may be provided for this purpose, but I find that the two jacks are satisfactory to effectively support the forward end of the platform as do the screws 8 and 9 at the rear of said platform. As indi ated, one of these jacks will be set forth in detail, such description applying to the other jack. The under side of the deck or platform near the front thereof has fastened thereto a bracket as 21 to which is pivoted the swivel member 22, to which in turn is jointed the bar 25 slotted for the passage of the bolt 24 and having teeth as 25 on its outer face for engagement by teeth as 26 on the head endof the bar 27, which latter is equipped with a swiveled foot; as 28 having a bearing, against the forward axle f. These jacks are located in line longitudinally respectively with the screws 8 and 9 and they form longitudinally adjustable supports, one of them being lengthened. while the other is shortened to a similar extent and which extent depends upon the amount of adjustment of the deck. When a jack is in operative position, the teeth 26 will be engaged with the teeth 25, a hand wheel or nut 29 on the bolt 24 bearin solidly at this time against the outer face of the bar 27. To effect the adjustment of the jack (5 the hand wheel or nut 28) is operated suiiiciently to disengage the teeth 26 from the teeth 25, at which time the deck or platforn'i can be brought to horizontal relation when the two hand wheels 29 are simultaneously set up. The two jacks, therefore, form elieetive longitudinally adjustable supports between the forward axle 4 and the for ward end of the deck or platform 2.

It will be understood that the slots in the bars 23 extend longitudinally thereof to providefor adjustment of the two jacks. The rear bolster Send the front bolster 5 are rigidly connected with the deck '2 in any desirable \'ay.
